Web
applications.
Client portals, internal tools, booking systems, real-time dashboards. Databases built to last, authentication, business integrations, from scoping to deployment.
Use cases
What needs does it cover?
A business problem before a technology choice. These are the projects that come up most often.
Client portals & member areas
Authentication, private data per user, differentiated access. A space where each client only sees what concerns them.
Internal tools & back offices
Inventory management, case tracking, workflow validation: replace the spreadsheet or no-code tool that has reached its limits.
Booking, ordering, payment
Online booking or ordering systems with integrated Stripe payment, as built for Restaurant Sakura.
Dashboards & real-time data
Interfaces that aggregate and visualize data, including from external APIs in real time, as built for Météo Explorer.
MVPs & start-up launches
A stack designed to move fast without sacrificing solidity: validate a product without rebuilding everything six months later.
Precision
This is not a showcase website
A showcase website presents a business. A web application makes it work. The difference is not cosmetic: it is a relational database that models your business rules, user accounts with permissions, and server logic that must remain consistent even when several people use it at the same time.
That layer, not the design, is what determines whether the project holds up over time.
What matters
What makes an application last
A database designed to last
PostgreSQL and Neon for a relational schema that models your business rules without technical debt from the first months.
Authentication & permissions
Accounts, roles and differentiated access handled properly from the design phase, with Payload or Supabase depending on the context.
Fast iteration, without debt
Every change is tested in an environment identical to production before going live: Vercel previews, Neon database branches.
Architecture that scales
From MVP to production usage, the infrastructure follows your application's growth without a complete rebuild.
Stack
Technical stack
Mature and proven building blocks, chosen for production reliability.
Concepts_Ref
Mission protocol
How does it work?
A transparent process, from business scoping to production deployment.
Scoping & modeling
We clarify the business need and model the data and user roles before writing a line of code.

FAQ
Frequently asked questions
01What is the difference between a showcase website and a web application?+
A showcase website presents a business. A web application makes it work. The difference is not cosmetic: it is a relational database that models your business rules, user accounts with permissions, and server logic that must remain consistent even when several people use it at the same time.
02What types of applications do you develop?+
Client portals with authentication, internal management tools, booking and ordering systems with integrated payment, data dashboards, and MVPs for start-ups. The scope adapts to the need, from a functional prototype to a production application.
03Is your stack suitable for launching an MVP quickly?+
Yes, that is a real strength of the stack: Supabase for authentication and a backend that can move quickly, Neon for databases duplicated by preview environment, Payload for an automatically generated back office, Vercel for continuous deployment. Enough to validate a product quickly without starting from scratch for the next version.
04Do you work with an existing database, or does everything need to be rebuilt?+
Both situations happen. An existing PostgreSQL or Supabase database can usually be reused and extended; otherwise, the structure is modeled from scratch according to your business rules.
05Do you provide maintenance and improvements after launch?+
Yes. I remain available after delivery for feature improvements, fixes, and questions related to infrastructure or performance.
